0.7 mm
Metal Refills sold only in Black at this time.
*All other Refills are plastic
These refills fit all of the stainless steel pens we carry
Stored in a paper sleeve (no blister packaging)
*We did a test with students and gave them a plastic pen, and a stainless pen, and asked what they do with them when they run out of ink.
Unequivocally they said they would throw the plastic pen "away", and were unsure of what to do with the stainless pen.
If we make refilling stainless steel pens easy and automatic, it's a step in the right direction.
If we can get to a point of recyclable metal ink cartridges, we'll be one step closer to closing that loop.
